It is what specialists call a Dutch Billy, a type of townhouse characterised by a stepped or curved gable facing the street rather than the pitched, hipped roofline that came to dominate Georgian Dublin. The form arrived in Ireland in the late seventeenth century, brought over in the wake of the Williamite wars and the movement of Protestant merchants and craftsmen who came with or followed William III. For a period, these gabled houses were thoroughly fashionable in the capital, lining the older commercial streets in considerable numbers before later tastes and later centuries reduced their presence to a scattered handful.

The Dutch Billy type takes its name from a popular nickname for King William himself, though the style had deep roots in Dutch and Flemish urban architecture long before it reached Irish shores. In Dublin, the form flourished roughly between the 1680s and the 1720s, after which the sweeping ambitions of Georgian planning gradually pushed it out of fashion and, eventually, out of existence. Most examples were demolished, altered beyond recognition, or simply absorbed into later developments. This particular house was noted by archaeologists Linzi Simpson and Ed O'Donovan in November 1997, who identified it as potentially dating from the late seventeenth or early eighteenth century. The qualification matters: Dutch Billy houses are notoriously difficult to date with precision, and fabric can be obscured by later render, altered windows, or modified interiors.

Because the exact address is not recorded in the available notes, locating this building requires some patience and a willingness to look upward rather than at eye level. In Dublin's older southside streets, particularly those that pre-date the Wide Streets Commission's interventions from the mid-eighteenth century onward, it is worth scanning rooflines for the telltale stepped or curvilinear gable that distinguishes this type. The survival rate of Dutch Billy houses in Dublin is low enough that any confirmed example carries genuine historical weight, not as a curiosity but as physical evidence of the city's pre-Georgian character. If you are moving through the area on foot, the upper storeys and the silhouette against the sky are where the story is told.
